perf: DEFLATE (puff) + -no-pie -> OF binary 879 KB -> 662 KB (-25%)
Two size wins:
- Replace the home-grown LZSS (2.0x) with DEFLATE: mktext gzips the text and
strips the gzip container to a raw DEFLATE stream; clectio decompresses it
with puff, Mark Adler's public-domain reference inflate (~200 lines, verified
byte-identical to gunzip on the OF/EF text, repetitive, random and empty
inputs). Text blob 671 KB -> 492 KB (OF), 164 KB -> 132 KB (EF), 2.7x.
- Build with -no-pie: clectio is a local CLI reading static embedded data with
no attack surface, so it needs no PIE/ASLR. The linker then bakes the string-
table pointers in at link time instead of emitting ~57 KB of runtime
relocations.
Net: OF 879 -> 662 KB, EF 266 -> 214 KB. Verified byte-identical to lectio.
The default build still needs only a compiler + libc; a CORPUS= rebuild now
also needs gzip. lz.h removed.
